Compressor Application Manual

3 - How to Remove the Filter Drier

Remember that changing the compressor also

requires a change of the filter drier, in the order

as follows:

Slowly warm the soldering region of the

capillary with the filter dryer and, at the same

time, pull the capillary with pliers, using

moderate force not to break it inside the filter

drier. Preferably, during the removal of the

capillary, make nitrogen circulate to prevent

the capillary end from blocking up.

After cooling, close off the end of the capillary

tube with a rubber plug.

Important comments

• Another procedure that normally prevents

blocking the capillary is to remove the end that

had been brazed to the filter drier. Using a file,

make a small groove around the capillary and

bend it until it breaks. Nevertheless, in cases of

successive re-operations of the same system, the

shortening of the tube will significantly alter the

capillary flow and jeopardize the performance of

the refrigeration system.

• When removing the filter, you must not heat it

unnecessarily otherwise water retained in it will

enter the system piping.

• Emission of CFCs (R 12, R 11 etc.) into the air

affects the ozone layer. Until a more effective

solution appears for collecting, recovering,

recycling and neutralizing the harmful effect of the

refrigerant, please attempt not to release CFCs

into the environment. Proper equipment is
